SASH.

Application filed January 24, 1928. Serial No. 249,030.

- My invention relates to window sash, and particularly to metal sash such as are used for holding. heavy plate glass used ink store front construction.

An object of my invention is to provide a sash which will hold the glass firmly but which will not subject it to rigid or unyield-k ing pressure which might cause breakage.

Another object of my invention is to provide a sash which is sufficiently small in -bulk to be applicable to bank doors or similar uses for which older constructions are ill adapted.

Still another object of my invention is to provide a sash which allows the glass to be lset without the use of any tools other than a screw driver, and whichinay be easily assembled in inverted position or in a cramped space.

MyV invention possesses other objects and valuable features, some of which will be set forth in the following description of my invention which is illustrated in the drawings forming part of the specification. It isto be understood. that I do not limit myself to the showing made by the said description and drawings, as I may adopt varying forms of my invention within the scope of the claims.

Referring to the drawings Fig. v1 is a sectional View of the assembled sash, the plane of section being normal to the surface of the glass. Y Y

Fig. 2 is an elevation of the assembled sash. Y I Y Y Fig. 3 is a` cross-sectional view of the stationary sash-bar, and Fig. 4 is a similar view of the movable sash-bar.

Fig. 5 is a view in plan of the clamp bracket, the direction of this vie-w being indicated by the arrow 5 of Fig. 3. y

Fig. 6 is an elevation of the movable sashbar, the direction of the view being shown by the arrow 6 of Fig. 4;.

In terms o-f broad inclusion, the sash of my invention comprises a stationary sash-bar which is provided with a lip or flange forV fitting against the glass, and is secured to the window frame.

from the stationary sash-baiat suitable in- Projecting past the glassA bar is that of the letter L whose foot rests on the clamp bracket. A lip is pro-vided on the riser of the L to seat against the glass, and a second lip or ange extends downwardly from the toe of the L to cover the ends of the brackets and complete the closure tothe window frame. Clamp screws pass thruthe foot `of the L and turn in nuts which enter the channel brackets as the screws are slid into t-he open slots and clamp the bar in place when the screws are tightened.V Means are provided for holding the screws in tension and preventing the nuts from turning, so

that the nuts readily; enter the channels rega-rdless of the position in which the sash-bar 1s held. There is no directlocalized pressure upon the glass, the resilience of the angle construction distributing the pressure gently thru the holes 13. The glass is supported' upon spaced blocks in theusual way, lthese blocks being omitted from the drawing to avoid confusion.'` Y Securely held against the stationary sashbar by the screws 11 are the clampingbrackets. The screws pass thru a tab 16 formed from an extension of the central web 17 of the U1 or channel section into which the brackets are formed. The web k17 has: 'ridges 18 at the sides, increasing in vheightl alongthe bracket, so that the web itself slopes down y and laway from the leg` 7 of the stationary bar. An open slot 19 is formed in the end of the bracket to admit a clamp screw, and the inner j face of the web 17 may conveniently be 'roughcned to form a seat for the Clamp-nut.` The 5 legs 21 of thefchannel rest on the foot 6 of the stationary bar, and are cut away to form agap 22 in the portion adjacent the slot 19;

VThe movable sash-bar is also Yof angle Aor L-sliaped section. Y The top of the leg 25 is bent back and down to form a flange 26 which seats against the glass. Both legs of the angle arepreferably provided with beads 27 to improve the strength andappearance of l lthe bar. `At intervals Vcorresponding with'l the spacing of the clamp brackets the foot 28 of the bar is. provided with countersunk holes 29 for preferably oval-headedcla-mpscrews 31. Threaded on the clamp screws and retained by upset ends 32 on the screws are the clamp-nuts 33. These are preferably rectangular inA shape and are provided with a tapered end 34 to facilitate their entrance into the space within the channel brackets. Secured to the clamp-nuts,.conveniently.by the rivets 36, are the leaf springs 37 which bear-against thefoot of the sash-bar and hold the screws 3l in tension. rllhe outer end of the foot 28 is bent to form a lip or ange 33, covering the ends of the brackets and completing the closure of the sash with the window frame 9. The springs 37 also serve to prevent the rotation of the nut 33 by bearing against this iiange. Small gaps 39 are formed at intervals inthe flange to provide drainage for the space within the sash.

Inhsetting the glass itis first positioned upon its blocks against the stationary sashbar, and then the movable sash-bar is slipped into place against it, the screws 31 entering the slots L19, and the clamp-nuts 33 sliding easily into place within the brackets due to theirbeing positioned by the springs. l/Vhen the movable bars are firmly pressed against the glass thescrews are tightened, and the operation iscomplete. rllhe resilience of the harstructure equalizes the pressure on the Cil glass and prevents breakage. The inclined seatformed for the clamp-nut on the brackets resultsinany slippin of the clamp increasing the 4tension on t e clamping screw, so that it jams against further movement, and thus provides a maximum of security with a very lightsimple, and compact structure.
